TYPE-MOLD.

BPECIFICATION forming part of Letters Patent No. 356,749, dated February 1, 1887.

Application filed Decemherflo, 1885. Serial No. 186,103.

To aZZ whom it may concern:

Beitknown that 1, JAMES M. CONNER, of the city, county, and State of New York, have in vented Improvements in the Construction of Molds for Casting Metal Type; and I do declare the following to be a full, clear, and correct description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a. top view of my improved mold. Fig. 2 is a view of one portion of the mold. Fig. 3 is a view of the other portion of the mold. Fig. 4: is a top View of the mold, the type having been removed threfrom. Fig. 5 is a cross-section on the line 56 .r, Fig. 1.

In the drawings like parts of the invention are designated by the same letters of reference.

The nature of the present in vent-ion relates to improvements, as hereinafter set fortlnin the construction of molds for casting metal type, the object of the invention being the production of a mold for casting metal type of the larger sizes-say, from what is technically known as fourlinepica. upward-by which the types are cast with a hollow body, by which the weight of the body. in each type cast is materially reduced. To accomplish this I combine with e. type-mold the movable prismatic strips, as hereinafter set forth.

To enable those skilled in the artsto make and use my inventioml will describe the same.

A and B show, respectively, the two sections of which the typemold is composed, and C shows the opening in the mold for the intro duotion of the molten metal from which the type is to be formed. The section A of the mold is provided with the strips on each side (No model.)

of a central plate, E, within which are fitted the movable prismatic strips D, the position of which to each other end to the mold may be regulated as required by the screws a.

E shows a type as cast in the mold.

The operation may be thus described: The mold and the movable prismatic strips are adjusted to the width of the type to be cast, the metal enters the mold through the opening 0, passes to the opposite side of the mold, and the letter is formed, the body of the letter being provided with the inclined sides extending from the central point to the base of the type and a jet formed of a strip depending from this central point and provided with e ball-like termination, as clearly shown in Figs. 2 and 5 of the drawings. After the type has been removed from the mold this jet may be broken off, and the result is a type the weight of which is materially reduced by reason of the hollow body formed as shown. Thus atype of less weight, and necessarily produced at a lower cost than if cast in the ordinary way, is produced.

Having now described my invention, I claim as new- Theconibinatiomwith a type-moldcomposed of the sections A and B, of the movable pris inzttic strips D, placed in advance of the open ing 0, and between it and the opposite side of the mold, and central plate, E, constructed and operating substantially as and for the purpose specified.
